Hi i ask'd the same question a while ago heres how you do it. Jack up car, take off wheel, put the weight on axle stand use your choks if youve got them or leave it in gear , remove the two bolts holding on the caliper remove the caliper,slide out the old pads push new pads back in.There are 2pots on the front caliper and one on the rear these need to be pushed back in to the caliper in order to slide back over the new pads and the disc,if you dont have the correct tool to do this i did it like so,i used me claw hammer's handle and placed it through the caliper and with a hand holdingboth sides of the caliper and hammer put enough pressure on them tosqueeze them down. once youve done that replace the caliper,bolts,wheel and repeat.i never did any thing like this before and found it easy to do.
